A junior developer caused an incident in production. How do you handle it?

The analysis of an incident caused by a junior developer in production should be constructive and educational:

1. Gathering information: find out exactly what happened, what changes were made, and how it affected the system.
2. Root cause analysis: determine why the error occurred — lack of knowledge, inattention, lack of checks, process issues.
3. Discussion with the developer: give them a chance to explain the situation and understand their point of view.
4. Developing solutions: identify how to prevent similar errors in the future — for example, implementing code reviews, automated tests, improving documentation or training.
5. Documentation: record the incident and lessons learned so the team can learn from mistakes.
6. Support: help the junior developer grow and not be afraid to admit mistakes.

It is important to avoid blame and to foster a culture of openness and continuous process improvement.
